Extra line break inserted after image

[Serranosoft]

When inserting an image, there is an extra <br> inserted after the image due to this line: exec('insertHTML', "<br/>");

This causes:

• Difficulty in placing images side by side.
• A degraded user experience when inserting multiple images consecutively.
• Therefore, the extra <br> is redundant and produces unwanted line breaks.

Expected behavior:

• Images should be inserted without adding extra line breaks.
• The cursor should remain correctly after each image.
