Comment 3 for bug 1551479

Requested file attached.

Note the only file format save option is JPG. Perhaps a conversion error
one might think. But:

1) Shopify Forum Expert states as per last post in link to Inkscape post
that Shopify does not convert images upon upload; and,

2) All other PNGs not created with Inkscape that were uploaded to same site
had no loss of transaparency or corruption, and after upload, only have JPG
as the file format option under "Save Image As . . . "

Hope this helps - James
