Is there any kind of way to change the size of the popup that ArcGIS Online displays in the maps/apps?
I want it so that there is no scrolling required to view the picture/thumbnail at the bottom.

What you'll have to do is host the pictures on an image hosting site, add a field to the table that you'll put the links to the pictures in. Then, in configure popup, at the bottom is a media section. Click Image, and change the Title field to list the name of the title field in your attribute table within these pointy brackets ---> {titleorwhatever} for the url, do the same {http://urlgoeshere.com/picturethatisonlyjpgor.png}
this will put the picture at the bottom of the popup. I don't know if you can modify that to put it at the top or not. Also, good luck getting it to show up in a web app, cause I have had none.
To do so you need to use ESRI's ArcGIS Online Assistant to edit the JSON that holds the pop-up template. Using the assistant your edits are not checked by ArcGIS Online and so anything is allowed. This also means that it is simple to corrupt map document if you are not careful.
- Go to: ESRI's ArcGIS Online Assistant and login to your ESRI account.
- From the "I want to..." menu select "View Items JSON"
- From the list on the left side select your map and wait for your maps JSON to load.
- When the JSON data loads on the right side navigate past the "Description" data and Edit the "Data" data.
- Find the line holding the pop-up configuration is question, remove the
target="_blank"and save your edits.
These edits will become live when saved however if you reopen the pop-up configuration in the Web Map Viewer in ArcGIS Online and make any edits the target="_blank" will be re-added to the template.

According to an ESRI source, there is still no way to resize a popup window in ArcGIS Online.

Hopefully (with the newest line of releases and ESRI's emphasis on "webmaps can do everything that Desktop can do"), we will see an update.
