Question posted in 
I am making a blog with huge ammount of images, and one way to do it, is by using Flickr Gallery plugin, which provides a functional gallery or your albumbs, but the links aren’t looking good (www…….5129512891.jpg), but they do have the proper alt tags (Red Carpet From Turkey).
So now I am wondering if I should stay with this Flickr gallery, because it eases my job thousand times, or I should look for a way to have both good link (www…….red-carpet-turkey.jpg) and an alt tag. (I am talking about a blog, primarily for images, not just here and there).
My goal is to appear in Google Images first, for example, when someone types “Red carpet from turkey”, and click on images, I want my pictures to be first in the results.

Both of them are important for SEO score. Its important to set alt tags and a related name for the image. You have to decide if its profitable to change every image name or let them as they are.
Take care with the image size, it matters too.
Google searches for keywords in the filename and in the alt tag for an image. It also searches relevancy information in the surrounding text (see here for image SEO – disclaimer I maintain that post).
Then you want a relevant filename, alt tag and surrounding text. You must make sure the quality of the image is good (Google checks it for ranking). You can also create an image sitemap to help crawlers find your images.
