** Why 16x16!? Because favicons (WWW website icons) are 16x16....Strongly suggest you make thumbs 16x16 and use thumbs.el and/or ImageMagick (free software) to make your table icons/thumbs all the same size:

apt-get install imagemagick
mogrify -format gif -path thumbs -thumbnail 16x16 *.jpg

Hello!

I was wondering if there is any useful way, to organize images in
tables. This would be useful e.g. if one needs to organize some images
on a regular grid, but the images aren't equally sized, such that a
simple line break doesn't do the trick.

Creating just a table with the image links inside will work
/basically/, assuming that the images have an appropriate size, but if
resizing is needed, I can't see how to do this in a table (because
inside no e.g.  #+ATTR_LATEX line is possible).

The same problem also occurs when I want to preview images side-by-side, e.g.

 :  [[./img1.png]] [[./img2.png]]

though here actually newlines from fill-paragraph/auto-fill add to the
problem - as will be the size of some high-resolution images.

My only current solution is to use explicit LaTeX and then preview the
LaTeX, but that slows down operation considerably.

Is anything currently implemented to allow such usage?
