  abstract = {1. {B}ackground: {W}hile many studies analyze the functions that images can fulfill during humanitarian crises or catastrophes, an understanding of how meaning is constructed in text-image relationships is lacking. {T}his article explores how discourses are produced using different types of text-image interactions. {I}t presents a case study focusing on a humanitarian crisis, more specifically the sexual transmission of {E}bola. 2. {M}ethods: {D}ata were processed both quantitatively and qualitatively through a keyword-based selection. {T}weets containing an image were retrieved from a database of 210,600 tweets containing the words "{E}bola" and "semen", in {E}nglish and in {F}rench, over the course of 12 months. {W}hen this first selection was crossed with the imperative of focusing on a specific thematic (the sexual transmission of {E}bola) and avoiding off-topic text-image relationships, it led to reducing the corpus to 182 tweets. 3. {R}esults: {T}he article proposes a four-category classification of text-image relationships. {T}heoretically, it provides original insights into how discourses are built in social media; it also highlights the semiotic significance of images in expressing an opinion or an emotion. 4. {C}onclusion: {T}he results suggest that the process of signification needs to be rethought: {C}ontent enhancement and dialogism through images have a bearing on {T}witter's use as a public sphere, such as credibilization of discourses or politicization of events. {T}his opens the way to a new, more comprehensive approach to the rhetorics of users on {T}witter.},
