Would it be possible for the search to show only a list of photo thumbnails?
Right now I have a situation where the first search page is empty (no albums are shown) and the images start from the second page. But I'd like the photos to show already on the first page

My search page code looks like this:

a href="">/a

Do i have to change something in the template-functions.php file?

You need to be using the $firstPageImages = normalizeColumns(ALBUMCOLUMNS, IMAGECOLUMNS); function combined with while (next_image(false, $firstPageImages)){

These control the how images and albums 'share' pages. You should look at one of the distributed themes for an example of a search page.
