Welcome to Fractal Forums

In Gallery in says "posting image size not to exceed 1200X 1200 pixels."  Now others get to post that size all the time.hmmn.  What's up with that?  Wrong format?  Do some members get more space because of their status?  ust tell me what size is acceptable for me to post.  Thanks soo much for your cooperation!  :dink:

the gallery and attachments are limited, including external images can be bigger....

Could you be more specific please?  For example I will try to post an image that is 1.26MB with a pixel size of 768X576  you will not accept it.  When you speak in generalities it is difficult for all.  

I think the problem may lie in your posting bmp files.

Try any other format!  Bitmaps (bmp) are not suitable for the internet at all - the file sizes in MB are just huge for the pixel dimensions.

I really think we should just disallow any bmp files in the gallery - it's a setting which can be adjusted easily enough.

Try opening any of your bmp files in your favorite image editor  (windows comes with mspaint for free in the "accessories" if you don't have one!) and save it out as a jpg or png file.  png is lossless, jpg can be lossy, but the difference is mostly seen exclusively in very large images, or animations.

After you save it as another format - compare the file sizes.  You'll see the bmp file is much larger, and therefore takes longer to load online and uses much more bandwidth.

I never recommend bmp for online posting.

You should have no problems with a 1200 x 1200 jpg or png - but a bmp at that resolution is just too much!

Hope that helps...

If it's still unclear - feel free to ask for further clarification   :crazy:

I'm posting png!  Thanks sockratease!

Ok png is with chaospro,, buuut chaoscope uses bitmaps!  And I do seem to have more problems with them not being accepted.

As I said ;

right, there are 2 limitations for uploading to the gallery:

the first is image size: 1200x1200 and the second limitation is file size: 1,2 MB ( in my eyes far to high but, some images really eat up 750kb easily ) so, 1,2 mb is the file limit


and i must admit, that i am very happy with this limitations, i have nightmares of people like you uploading massively large files with really low informational content ( the amount that remains after compression ) file size is limited, and it works only if rigorous filters are set, because nowadays we can not check every single upload for file sizes

and i will go and remove the "BMP" file format from the allowed file formats in the gallerry ...


ARGH, BMP and INTERNET

Use RIOT to compress efficiently to jpg without much perceptual quality loss. That image can be compressed to 50-60kb or even lower easily, that's about 1/20th of the bmp size.  O0

Edit: Sorry I meant to post that in this thread: http://www.fractalforums.com/images-showcase-(rate-my-fractal)/icon-t3398/?topicseen but I guess it's just as relevant here.

Thanks for the info.

RIOT is used by IRFANVIEW Internally

Was the image size limit changed, iirc i have seen different sizes last time i uploaded an image?

yes, i have silently increased image sizes, to 2400x2400, max file size is 1,2 mb ( do not exceed that )
if the gallery does not scale down uploaded images, it can handle big files ...

and i wanted to allow desktop size images ( 1920x1280 ) but i did it silently to check if it works or
make other problems.... but it seems to work

I tried to post an image in a reply. Problem is it only allows 256KB.  Sorry folks but have no idea what that is.  I know jpeg, bitmap, png.  So when i tried to make it smaller repeatedly I got the message that I had already tried previously, soo rejected. Yes I must be an alien here! :alien:

What, you don't know the latest 256KB image format ???

No, seriously, 256KB means 256 Kilobytes : it's the maximum file size allowed to attach a file to a reply. Your file was too big. So use the gallery instead of posting the image directly in the reply, and paste the gallery link in your reply.

hope that helps

Hmm, actually it is 1.14 mb, but there seems to be another issue, when i tried uploading a 1800x1280 pix image
with 1.12 mb, it just says: Error 500 - Internal server error
 

That happened to me as well, only in German.[Luckily I speak German]  My image was 1500x1500 and less than 1.2mb

Trifox is on Holiday just now.

I'm sure he'll look into it when he gets back  O0

Thanks bib!  KB that term is not used in the USA with fractal programs as far as I know.   Also I just downloaded Caoscope &  I remember somewhere here the powers that be had a hissy about a member using Bitmap images.  Problem is that chaoscope only renders with bitmaps.  Are they the evil program? :evil1:

I just changed an image from bitmap to jpg 1200X1280 & it still is refused for this forum.  things that make ya go hmmn

What is the file size (MB)?

Kilobytes = KB 0 - 1,023
Megabytes = MB 1,024 - 1048,576
Gigabytes = GB 1,048,575 - 1,073,741,823
(approximate values?)

Anyways right clicking on any image in the files will show the size of the image.
Use a paint program to resize it, like Gimp or paint.net.

Choose .jpg and decrease the size to show the quality in a viewer.
I think the size needs to be 1000 x1000 or less considering 72 ppi (pixels per inch) or dpi (dots per inch) Same thing.
The size must not exceed  about 1MB  I think it's 1.14MB

I hope this helps people.

Did this help anyone?
BMP always holds every single dpi as a value in memory
JPG compresses them and makes them take up less memory by "combining" pixels into each other so fewer pixels need to be stored in memory.  It uses a technique that at at a higher level an eye wont notice any loss of detail, usually 80% and up is good but I have had to make it even smaller sometimes.  Usually if you "save for the web" (an option in photoshop) it tells you the size of your files and allows you to compress it further.

BTW, I have had no problems posting in the gallery following those rules I mentioned above, AND;  I only link to files in posts. I never attach files to posts because I know how screwed up it makes the whole database if they get deleted, lost, or corrupted.  I would suggest not allowing attachments in posts.

thunderwave somewhat helpful :)  The main problem as I see it it that what your saying is not general knowledge.  Also when posting an image in gallery it just mentions the pixil size now 2400x2400?  soo ya wait & wait then finally ya get told that the Mb is too large. Also for example an 800x600 image will show having 1.37MB?  but when I go to pqint to eresize i can only resize with pixels.   Newbies are not gona have a clue.- :hmh: nor should they.

I ran some tests,  anything at 1.14MB or less and larger then 1000 x 1000 brought up the error page no matter the dimensions I used  (3200 x 3200, 2400 x2400, 1200 x 1200). Interesting I also got an error about not having a title, my title was "test".  I renamed it "test01" got the error message "Must have a title".

if the image was 1000 x 1000, but larger then 1.14MB it said Image too large.
Anything at or less 1000 x 1000 dimensions and 1.14 and smaller went through.

So to struggle with getting an image smaller then 1.14 and the 1000 x 1000 dimensions you have to play with the quality of the image.  Which means sliding down the quality of the .jpg file until it's at 1.14MB or less.  Does paint.net, or gimp do this?   I only use Photoshop.

Ahh now we are on the same page! :dink:  And yes quality goes down with each attempt. :sad1:

There are other ways to get the image size to go down,  In Photoshop, I tried clicking progressive in the save for web, as well as adding a slight blur to it, you can then balance between blur and quality.

As mentioned earlier, Trifox is away on holiday and will deal with these issues when he returns.  Earlier in this thread he describes what he was doing to the settings, so keeping within those parameters should avoid any problems.

Of course, if you find the file size limitations too restrictive, you can always host the images externally to the site! 

hi there, the problem is that the server cant deal with such big images, * php memory restrictions *

i just thought it could work when scaling was disabled, so it is a pitty, but i will reset the image sizes
to as they where before, when i am back home next week :) the hotel has nice internet acess here in poland/gdansk :D

cheers

256KB refers to memory size of the image not format, 256KB in any Format is 256KB, compress it in memory size not Dimensions.

Thank you for the help, I hope you are enjoying your holiday.
