on my application the user plugs a camara to the computer and scans a document. based on that scanning number a folder is created and the folder where the camara holds the pictures opens up for the user to select which picture(s) he/she wants to transfer over.
using the dialog.vi and with multi-select iam able to have the pictures on thumbnail and have the user select 1 or more pictures.
I would like to go a step further; increase the dialog size (the square region) and instead of having the user drag more than 1 picture have labview show the pictures in thumbnails with a check mark on the side.
i will read some more on the call library function node.vi
here are pictures to hopefully show what i would like to achieve.
any help in this will be apreaciated.

One option would be to do what you did until now, but change the file selection window to show thumbnails. It looks like you can find an example here - http://forums.ni.com/t5/LabVIEW/View-Thumbnails-in-Open-Dialog/m-p/1060151#M470633
Another option is to do this yourself - create a 2D array of clusters where each cluster includes a boolean (for the selection) and a picture indicator and resize it yourself. There's code for resizing the images here - http://forums.ni.com/t5/LabVIEW/How-to-Resize-a-picture/m-p/246878?view=by_date_ascending#M133902
