Adobe Captivate is a software program primarily used for creating eLearning content. It supports various image file formats such as JPG, BMP, and GIF, which can be imported and used within the program. However, PSD (Photoshop Document) files, which are native to Adobe Photoshop, cannot be directly used in Adobe Captivate. PSD files may need to be converted to a compatible format before they can be imported and utilized in Adobe Captivate.
