This is in a CTF Context. We need to make the complete meaningful sentence by read aloud the separated unrelative words.
These are the given words: Green Dye, Red Dye, Lapis Lazuli and Windows Panel. You can try matching by pronounce or color, ... any way to get close to the result.

الإجابة

This is a Mad Gab–style phonetic puzzle: replace the objects with short spoken descriptions, then say them quickly until they merge into a sentence. (UltraBoardGames)

The useful substitutions are:

ImageLikely spoken formBecomes
Green Dyegreen ink“grinning” or “Greek in”
Lapis Lazuliblue ink / blue stonepossibly “blinking”
Red Dyered ink“reading”
Glass Paneglass“class” or “glasses”

The clearest section is the final three images:

red ink — green ink — glass
reading — Greek in — class

So the strongest decoding is:

“…reading Greek in class.”

The preceding pair also works:

red ink — glass → reading glasses

Therefore, the sentence most likely ends:

“…reading glasses, reading Greek in class.”

The first three images produce something close to:

green ink — blue ink — green ink
grinning — blinking — …

but the third part does not resolve cleanly enough to claim a unique complete sentence. Since the card is marked 1/5, the other four panels or the expected CTF flag format are probably needed to determine the opening clause.
