Mapping Images to the proper field in CMS collection

Hi everyone,

I’m having a bit of difficulty assigning images imported with CSV into the image field in CMS Collection. Not sure what I am doing wrong as I’m able to assign the rest of the content other than the images and the date.

I have tried several options while making sure the .jpg files are less than 4mb and the URL links added to CSV are saved correctly but this didn’t solve it, although I was able to upload the images directly to each blog post items. However, I’m 100% sure there is quicker way to do this. Please help
