Uploading photographs
I did find a bug related to large file sizes. Reducing to 640x480 would have got around this. Images don't need to be set sizes, but the bigger the file size the slower it will be to upload.
In internet Explorer you also don't get any progress indicator, so smaller Images save you doubting if it's actually working!
Also, I know some people have been having trouble modifying Images on posts (including blogs), this I hope is rectified too now.
Thanks,
Stephen
