There are 3 main ways to upload photos to your Picasa Web Albums:
Uploading several photos at a time
The fastest way to upload photos to your Picasa Web albums is by using the multi-select feature of the Local Photo Selector. To do so, choose Local Pictures from the main menu, then select a time range.
In the Local Photo Selector view, tap the Upload icon (upwards pointing arrow). On older Android versions (2.3.x), tap the Menu button and choose Upload.
The screen will switch to the multi-select mode and show Upload, Select all and Cancel buttons. Tap on every photo that you want to upload to select it. The selected ones will be shown with a green border, as illustrated below.
Finally, tap the Upload button. This will trigger the upload process in the background, so you can continue to use the app while the photos are uploaded to your default Picasa Album.
Please note that the photos already uploaded to a Picasa Web album are shown with a small Picasa icon in the bottom-left. This is in order to help you avoid uploading the same photo twice.
Uploading existing photos one by one
If you don't have a lot of photos, you can upload them one by one. You can do so either in the Local Photo Selector view, or in the Local Photo Browser view.
In the Local Photo Selector, long-press on the thumbnail of the photo you want to upload. From the context menu that appears, choose Upload.
In the Local Photo Browser, tap the Menu button to open the options menu. From the options menu that appears, choose Upload.
If you want to upload your photo shots to your default Picasa Web album the moment you take them, your best bet is to use the Camera option from the app's main menu.
Please note that, by default, a local copy of your photo shot is created only if the upload fails (you can change the default behaviour from the app's Settings menu.)
The auto-upload feature is intended for users who want to take photos using other apps, but still upload them automatically to their default Picasa Web album.
Please note that, in order to conserve battery, the auto-upload feature is not turned on by default. To use it, you have to enable it from Settings -> Uploads.
In this screen, you can also specify the default time interval at which PicsPro for Picasa scans for new photos to upload.
Please note that, while the scan itself is very fast, uploading photos may take a while, depending on the number and size of your photos, as well as the speed of your internet connection.
For this reason, we strongly recommend turning off the auto-upload feature when you no longer need it.
