Thank you EVERYONE for your comments on my last post. I appreciate the suggestions and help you offered.
A few of you mentioned you could not see any lines through my pics. That was probably due to the fact I had to upload them at least five times each before they were even close to presentable.
The pic below is an example of the problem I am having when I upload.
I don't believe it is a prob with my camera or scanner. And it never, ever
used to happen before and I do not seem to have the problems with any other place other than Blogger.
The caravan and the dog both uploaded, no lines on the first try.
Both 900 x 676 pix and high quality files???
This one has the lines too.
With the two pics below I went back into photoshop and made them smaller still,
700 x 576 pix and saved them as medium files. They uploaded first time without the lines.
Hopefully I have a fix!!
