Adding image (English version of the page) to 114 WordPress pages

We have 114 translated pages (from ENG to SPA). Each translated Spanish page requires an image with the link to the corresponding English page. You should manually add an image with the correct link to the corresponding page in English. It would take about 1-2 min to open a page and add this HTML code (which you can copy-paste) at the very beginning of the page in the top left corner of the page. The whole work could be done in 2-3 hours . The difference in the HTML codes for different pages will relate only to the URL of the page in English. Otherwise, it will be the same code related to the image and alt tag (something like "in English", or "en Inglés"). The code should be at the very beginning of each page in the top right corner. I provide you the image itself and the list of 101 Spanish published URLs. And you will find 13 draft pages to do the same with them too. The suggested bid for the project is 20 USD.
