Nancy Jo, I use photobucket.com to host my photos and after I upload the photos to photobucket, I copy the html to put into the blog post and where it says border="0" alt=blah blah blah, between the two I type in width="400" height="299" for horizontal pics and width="400" height="512" for vertical. That is the size that fits my blog the best. The numbers mean pixels and you can just play around and see what fits best for your blog. Hope that's clear as mud! :-)
Hi Nancy Jo, Making bigger pictures eh. Well I had that problem and some one told me that before I published the blog to right click on the picture and along the bottome of the pic would be large x-large pic size etc just sizes and then you click on the size you want and it just worked. Well It worked on my one blog but not the other and they both were blogger--so go figure. but anyway try it and see what happens. MB
