I would be more worried if the blotted area was different (the dark blob) - or if data in a datasheet (something like test specificity, level of detection, etc) was wrong

Now, if while preparing the images they needed to do some editorial choices (or it is well possible a person in the editorial group was told to 'enhance the images' but wasn't aware of the details) because of limitations in doing the experiment then this is probably not a big deal

Or if more than one blob is present (i.e. blobs at different molecular weights) for a supposedly selective and specific antibody that should show exactly one blob on the blot.

Editorial choices on raw scientific data are a big no-no.

I don't think you can find a picture in an article that hasn't been photoshopped in one way or another (which is mostly ok as long as it is not misleading)

Basically they say they are reviewing the images

Usually, journals require raw, unmodified data to be deposited as supplementary information.

Yes, as supplementary information

(Also journals are usually more rigorous than marketing material)

Still part of the article.

Do you work in biology?

These images are provided on the datasheet and form the basis for the level of detection / specificity claims

It is obvious that they edited the images to make blobs look shorter vertically. And in some cases, simply copy-pasted non-existing blobs.
