Given a text file like the following, just import the file and let it place your points based on the lat/lon values. using the XY Table to Point tool.
Lat | Lon | Company | Logo URL |
-40.5 | 88 | Company 1 | somewebsite.com/image.png |
-43 | 82 | Company 2 | somewebsite.com/image2.png |
You can use the associated URL field to get the logos into a web map / popup / etc.
If you actually want to add the file to your layer, you need to enable attachments and add each of them. Depending on the number of companies in your layer, this could be quite tedious.
