Pulling different images using keywords from a list

[Maxcba]

I'm currently trying to use icrawler to download images working through a list for each of its keywords. The issue I'm having is that as I only want one picture for each keyword icrawler sometimes downloads two images for 1 keyword then none for another. Looking into the shell while its running I can see that the download is called before the parser which is causing the issue but I have no idea how to dix this. Any help would be much appreciated.
