It looks like the TexturePacker program includes the ability to process images from the command-line, which you could then batch process with a script. You'll first want to install the utility by clicking Install Command Line Tool under the TexturePacker menu in the app.

Then I'd suggest having a look at the documentation, which includes the command-line parameters for most of the options in the app. Have a look at that, and see if you can get  the actions you need on the command-line. If you need help turning those into a batch processing script, I'd suggest coming back and amending your question with the specifics.

Should I use Automator or another program for repetitious tasks?
I am able to connect to a specific MS Access Database when it is on the same Windows computer as Mathematica via the command

&lt;&lt; DatabaseLink`;
conn = OpenSQLConnection[JDBC["odbc", "Databasename"]];


However, I cannot figure out how to connect to this database over a local area network -- disregarding trivial network problems (the computers can ping eachother), is this even possible?
