I was having issues earlier on Firefox. It wasn't rejecting my images but just wasn't loading them properly, which had never been an issue before. When I switched to Internet Explorer it ended up working.
is your blogger picasa album full?? that might be causing it....
I used to have issues so now I use Windows live Writter. It is amazing! My pictures download fast and I've never had a problem. Oh and the program is free!
try deleting the cookies in you computer. when mine gets overloaded with junk this happens. I also use Firefox, less issues here. If nothing works then I upload to picasa first, then do the upload from picasa in blogger. good luck!
Yes, I too have had some trouble with picture uploads. And terrible problems with blogger updating my blog roll!!
Thanks for stopping by! I'm so glad you did. :)
