Did not work for me. Still having the HTTP error
wow thats funny. I took a file that I was trying to upload that was 1280x1024px and made it 500×1024 and it made a thumbnail just fine. I actually made the filesize larger as well just to make sure it was not filesize. I wonder if its some hard coded value in there that we or they can change.
So really the only way to make it so I can upload large images in 2.5 is to contact my host and see if they can give me access to more CPU and ram? What is so different about 2.5 that makes it this way? Before I upgraded I had no trouble with uploading and making thumbs out of large images.
