How to make a calendar with a picture?

There are numerous ways to make a monthly or yearly table. Spreadsheet software like MS Excel is a popular choice. Writing programs like MS Word can do that too. And dozens of drawing programs and so on and on.

There is a learning curve to making a table, but it should not be too much work even for beginners. I believe it's worth investing a couple of hours in LibreOffice because with this package you get everything MS Office offers but completely free! Yes, thousands of free fonts are included.

If you don't want to learn and prefer quick results, there are also many free calendar templates for LibreOfice available. In this case, you'll be limited to design, language, typography, etc., yet probably satisfied to a reasonable extent.

If you don't want to use LibreOffice, use any other program, where you can make a table (many are available online, so you don't even have to install anything and simply create something useful on the go, or just download an already-made table from one of the numerous free graphic resources.

If not for the table, you'll need one for a photo, an illustration, or another kind of image that will complement your table. While a table with dates is definitely enough for a useful calendar, it will undoubtedly look way better with pictures.

My go-to address for photos is always Pixabay. It's not just a great depository of impressive photos in high quality, it's also very useful due to its copyright policy. All images downloaded from Pixabay are free, they can be used for anything you want (except some illegal activities), and you don't have to worry about crediting the author (you are still encouraged to do that). You don't have to count the number of visitors to your page, report buyers of your calendars with pics, and similar technical stuff that can often destroy small businesses even before any kind of profit is made.

LibreOffice offers many ways to combine table(s) and picture(s) in Calc, Writer, or Draw but I prefer to use Inkscape. This is another free and open-source alternative to otherwise very powerful, very user-friendly (I admit, more than Inkscape), and very expensive Adobe Illustrator (which, by the way, is available through subscription only, what means you can't even buy it and deal with the costs once and for all).

Inkscape is way more demanding for beginners than LibreOffice programs but there are tons of learning materials on YouTube and for a simple project like making a calendar with a picture, you'll probably know enough in a couple of hours. Basically, you just have to import the table and the picture and then add the tile (Calendar 2023, for instance). All three elements should be appropriately formatted, where Inkscape's ability to resize the elements could play a huge part, and finally aligned due to your preferences (I like elements to be centered).

Your final design, if any good, will be eventually printed on paper. This means you'll have to format the file with your calendar to fit (in most cases) to A4 or letter format (first for European, the second for USA standard, and no, they are not the same, although quite similar).

I mostly use the format with 2100 pixels width and 3100 pixels height for vertical and vice versa for horizontal designs.

Such formats make very large files and if you want to present them on a web page, you'll have to resolve several technical problems. You'll have to know a bit about different graphic formats and compression methods. You'll also have to find a good compromise between speed and quality, or, if you want, resolve an interesting dilemma - would you like to make happy your visitors or Google bots?

Will you provide speed or quality?
