I have had problems with uploading images to Blogger. In the past they would accept documents sized at 75 dpi or smaller. My scanner's smallest setting is 75 dpi.
I went on the Blogger Help function and now see that they want the image size to be 50 dpi or smaller.
I will have to teach myself how to make the image size smaller in Photoshop, I guess.
I assume this is why I have not been able to upload images to Blogger.
I am way behind in posting my ATCs to this blog due to this Blogger photo uploading issue. Sorry!
