Like you said, text can do alot in describing a story or environment, don't feel obliged to put photos or take pictures on purpose for an article, it would be nicer, but like you said, you start to put alot of tought into it and might get a bit lost in the intention of the article / text or not be satisfied with the quality of the photos.
I would sugest either not giving to much importance to taking the photos themselves (since writing might be your best side) by looking at free stock photos sites you can use (i can't recomend much, but pixabay comes to mind from other users and there are more) or also explore Creative Commons images that have a specific license were you can earn with them, (CCBYSA, etc).

I think most of the times people that write use the images to put a bit of a mood to the post, many do not use them to actually describe the writing itself but maybe some of the feelings ;)

PS: In hive something came up which i found cool, #hivestockphotos, not for here, but i liked the idea and gave it a try and shared some of the profits of the text.
