I've tried a couple times to upload pictures and I keep getting a security error message. Has anyone else had this problem?
There is a file size cap, not sure if that is your issue, there was a thread a few posts back in this section about this issue: https://www.canonforums.com/threads/i-was-unable-to-upload-some-pics.574/
Sorry, yes we believe that the file size cap is the issue. I haven't had a chance to change the file size limit on the server. Will try to do it this week!
Can you try to upload the photo again? I increased the upload limit on the server to try to fix the issue
I was able to upload only one image, a very heavy crop only 4.8mb file. I tried other images but got the same error message but they were all larger file sizes 10.5 to 37mb files
+Have you tried to convert them to a gif file, I had the same problem and this has helped, there are free programs on the internet if you don't have one.
JPG is far better suited for photos, the P stands for photographic. It supports 16million colors where gif supports 256 colors. Jpg uses lossy compression and the user can control the balance between size and quality, generally you will see better quality and smaller sizes. It would be my recommended file output resized down for web.
you are very correct in what you are saying they are superior but when they will not load this is one way around the problem by using a less complex file
Scale your photos to a web-friendly resolution and you should be good to go. If the file is 10-37 Mb then it's also going to have a very high resolution. Something like 1200x800 or 1400x900 is perfect for forums.
