web crawlers – Could allowing our images to be indexed hurt our web search rankings?

We are trying to solve some issues related to our SEO. When we compare ourselves to our competitors who are higher that us in SERPS, other than more backlinks (not much more), we don’t see any significant differences. One thing that caught our attention, though, is that images are not being indexed for our competitors and they are for our site. So, we don’t really know if it may be affecting our rankings.

So, the question is, is it possible that having multiple images and not preventing them from being crawled is affecting our rankings because, for some reason, our crawl budget is exceeded due to the images?
