I typed in the following and got a lot of info: <span id="INSERTION_MARKER">picture frames 300 x 300 with Google. You might also try it with Amazon - they seem to have some of everything these days.
I'm convinced that this must be possible here in 2014--somehow, someway--without needing a degree in programming:
I've been curating and tracking down cover art images with the specific dimensions of 300x300 to add to my MP3s has been arduous.
Surely there must be a shortcut to do this without having to either append gobbledey-**** to my search result URL ("&tbs=islt:2mp,isz:ex,iszw:300,iszh:300") or going through all the steps of filtering results (Google> Images> Search Tools> Size> Exactly> 300> 300....) via a Permalink using google keyword operators, or Chrome Custom Search terms, or... SOMETHING!
I've spent the better half of the day looking into this and found very little of any use. Someone out there in CNET land must know the secret; I beg you, I'm a desperate, defeated man.
