How to make date etc appear on back of photos

Once the photo is date stamped that is a done deal no changing it.

The date and time (and a lot more) are stored with every photo in its EXIF metadata. If you want the date printed on your photos then please refer to the documentation for whatever program you're using to print. Depending on the program and printer you may have the option of printing the date on the image, in the margins, or on the back.

theres no date a time stamp on the photo itself with DSLRs but the meta data is kept on file in the photo so it has recorderd the time and date. depending on what photo printing software your using you can bring up the time and date back on the photo. I have canon photo printer and using the bundled software easy photo print, it allows me to print time and date of the photo. or if you use adobe lightroom you can get the time and date back on the photo. the time and date stamp is more of a compact camera rather than DSLR.

The date, time, lens, camera make and model, etc. is already included along with each picture file...it's called "metadata".

Are you sure your canon battery pack is OK?If not ,replace it with a high quality replacement battery pack.

The date and time (and a lot more) are stored with every picture in its EXIF metadata. Any photo viewing/editing program should be able to display this data. To print this data, please consult the documentation for whatever program you're using to print your pictures. Depending on the program and printer you may print the date on the image, in the margins, or on the back.

Set the image size to 'postcard'. Press the Function key, scroll down to the bottom icon and select postcard (L, M1, M2, S, postcard). Press Function key again.

To turn the date imprint on, go to the Record menu and set the option for Date Stamp to Date or Date & Time.

I believe you are referring to the PowerShot SX100 IS, as there is no SD100 IS. And yes, it does have the date stamp option while the image size is set to the postcard mode.

Check the options carefully, and read the manual.If you don't have a manual, they are free for the download at Sony. Look for you camera under support/downloads.
Some cameras only allow date and time stamp to be in certain resolution settings. It will not show up in other photo size settings.

this camera has an internal clock battery, which must keep the date or any other related information while you changing the batteries, the problem is, since you camera is pretty old, the clock battery is probably long dead, it can be changed, but it will require disassembling and resoldering
