How to create macro in photoshop

[Rachel23136304plii]

Hi, once I have the photoshop image ready, I usually create one large and one small jpg (export) files. As I have many to do, it is becoming time consuming process. Is there a way I can create a key stroke function with specified settings with one macro or preset (not sure what the terminolgy is for this function). Example, I export as jpg with specific image sizes, canvas size...all these settings are saved as one preset button function.

Thanks

Have you looked in Actions yet?

Although an Action is a "macro", what you describe will need to be performed using two separate runs with the Batch (Action) command with two different actions for Low Res and High Res, which will play the action and allow you to resize and rename the two files differently or to save to two separate output directories with the same name. So you will first create the two actions, then run them one at a time with two different batch settings:

This could also be performed using the Image Processor Pro script, which will allow you to create two separate "sets" to save, resize and or and rename in a single run of the script without the use of an action (although it can run an action too).
