If you want to dig further, you can look for image tags in SVG, reject all lines containing the "provided by" string, and see what the others are.
There're 2470 images containing <image (852 current, 1618 old) and 1402 (601 current, 801 old) with a data: url (xlink:href="data).
But not all of them are bad just for having an image. Another use case than translating are maps. http://commons.wikimedia.org/wiki/Image:Arnica_Montana_Culture_In_Scotland-f... is an example, but there're others there using raster images to mark points in the map. What we do not want is a map containing the map as raster.
For now, it'd need to be manually checked case by case (Wiki-Bot can give notices for them) which is quite unpractical. Perhaps we could set some threshold, such as marking for review SVGs containing a raster and less than X svg tags. Another could be rendering them twice, with and without rasters, so a human could check really fast which portion is svg and which not.
Search for "provided by" yields 63 results, which are the same as those with 'texture provided' plus http://upload.wikimedia.org/wikipedia/commons/8/84/8_Meaning_of_Constraint.s..., which is a false positive ("provided by function 1").
